    Notes: Summary Vimentin immunoreactivity was examined in brain tissues from non-neurological and various human central nervous system disease cases. In all brain tissues examined, vimentin immunoreactivity was intensely positive in ependymal cells and subpial tissues, and weakly positive in some capillaries and some white matter astrocytes. In affected areas of Alzheimer's disease (AD), Pick's disease, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) and cerebral infarction cases, numerous intensely vimentin-immunopositive astrocytes of both protoplasmic and fibrous morphology were demonstrated. A few such astrocytes were also observed in Parkinson's disease and progressive supranuclear palsy. ALS, MS and infarction brains also had numerous, strongly vimentin-positive, round and fat-laden microglia/macrophages. In AD and ALS, a few reactive microglia with irregularly enlarged shapes were vimentin positive. In AD, they were almost exclusively related to senile plaques.

    Notes: Summary The previously reported unusual, Tau-positive glia with astrocytic morphology seen in brain tissues from cases of progressive supranuclear palsy (PSP) were re-examined immunohistochemically using antibodies to CD44 and vimentin, as well as Alz-50. Four brains of PSP cases, one of whom had atypical clinical features, were examined. All four cases showed the unusual glia which were positive to Alz-50 and anti-CD44 antibodies, but negative to anti-vimentin antibody. Ultrastructurally, they had either paired nucleated or lobulated nuclei and the cytoplasm frequently contained lipofuscin pigment. The CD44 was located on the surface of the cell bodies and their processes. Such glia were most numerous in the striatum in all cases. They also appeared in the cortex and some subcortical nuclei in the three typical cases. They were not seen in the lower brain stem or cerebellum. In their morphological characteristics and regionally specific appearance, these unusual glia seemed similar to the Alzheimer type I glia which are commonly seen in hepatic encephalopathy or Wilson's disease.

    Notes: Abstract Cholesteryl ester transfer protein (CETP) is a plasma glycoprotein that facilitates the transfer of cholesteryl esters, phospholipids and triglycerides between the lipoproteins, and regulates plasma high-density lipoprotein levels. We examined CETP-like immunolabeling in non-neurological and Alzheimer's disease (AD) liver and brain tissues. The anti-CETP antibodies showed positive staining in round cells in the liver sinusoid and in brain astrocytes. In the brains of non-neurological cases, positively stained astrocytes were preferentially distributed in the white matter. In AD tissue, many reactive astrocytes in the gray matter as well as the white matter astrocytes had CETP-like immunoreactivity. CETP-positive astrocytes may play a role for AD pathology such as tissue repair.
